CELL-CASE MACHINE.

fb all 'whom z't may concern Be it known that I, ALwIN W. D. VaIs, a

citizen of the United States, residing at Waterloo, in the .county of Blackhawk and State ofl'wa, .have invented certain new and useful Improvements in Cell-Case Machines, of which the following is a specifi- This invention relates to .cell-case machines, and more particularly that class of machines used in the manufacture of eggcase fillers. 1

The type of machine herein shown is what is known as the two-roll type, and the main objects of the invention are: to provide mechanism whereby the cut and punched filled strips may be fed intermittently into suitable strip-carriers arranged in a chain or gang having a steady'and continuous forward movement, to improve such Stripcarriers, and more particularly the stripholding fingers.

The full nature of the invention will clearly appear in the description and claims following, reference 4being had to the accompanying drawings, in which Figure 1 is a general side view of a machine embodying' -my improvements. Fig. 2 is a fragmentary longitudinal section, showing 'more particularly the ejector mechanism. Fig. 2a isa fragment, showing the attachment of the ejector lever tothe main frame. Fig. 3 is a perspective View, showing the strip-conveyer and related mechacross-shaft 5.

nism. Fig. 4 is al plan view of an intermatched cell-case, and shows the position of the ejector and its push-pins in relation thereto. Fig. 5 is a fragmentary side View illustrating the main driving gear and the quarter-turn device. Fig. 6 is a plan view of the latter.` Fig." 7 is a detail illustrating the improved vstrip-holding fingers, and also the natural curvature of said strip as taken from near the core of the roll.

ln the main the machine is of a familiar. type and needs but to be briefly described, in order to a full understandingr of the improve-` ments involved in this invention. For the most part a description of one half will suftice, since the two ends ofthe machine are almost exact duplicates.

On suitable main frames l are mounted the punches and cutters 2, coperating with suitable dies 3, the punching and cuttingr head being rcciprocated by ecccntrics 4 on a These cross-shafts, of which Specification of Lettels Patent.

there is one near each end of the machine,

shaft 7. On one ofthe cross-shafts is mounted the main driving pulley 8. The

cross-shafts are also provided with small.

sprockets 9 communicating by chain-belts 10 with large sprockets 11 on one of a pair of roll-shafts 12, which are thus given aslow but continuous rot-ation. run at a suitable surface speed to supply slack paper to the intermittent rolls 13, driven by the usual ratchet and pawl mechanism 14, r0ds15 and'cranks 16 on the shafts 5, Back of thecontinuous feed-rolls ,are -provided with bevel .gearing 6 having., concurrent motion through a longitudinal These rolls is a tension device 17, forming no essential feature of this invention. From the foregoing it vwill be seen that paper from theA rolls 18 will be fed under the punches intermittently, and there punched and cut off in the usual way. i

In the middle of the main frame is mounted the gang'of strip carriers 19, provided with the ugual strip-holding clips 20, and mounted revolubly each on a link of a sprocket chain 21', Throughout'the most of their course. these strip-carriers run between guides 22,' which serve to keep them in exact position at all times. The carrier chains are mounted on large sprockets 23 on shafts 24, one of which is provided with a wormgear 25 engaging a worm 26 on ashaft 27 driven by spur gears 28, one of which is fixed to the longitudinal shaft 7. The gearing is so calculated as to impart continuous motion to the'strip-carriers, and at such a speed that at each cut-oli' of a strip the carriers'have advanced exactly the distance of the space between strip centers in the finished cell-case. By means of strip-transferring'mechanism Ato be described presently the carriers at one side ofthe machine are successively filled with horizontal rows of strips, after which each carrier is turned one quarter around, and on the other side of the machine is filled with intermatching strips in the lsame manner. The quarter-turning device is best shown in Figs.. 5 and 6. It comprises an arm 2S) pivoted at 30 on a curved extension 31 of one of the guides 22,-

and provided with a roller 32 lying normally in the path of the advancing carrier.

near one sidez A spring 33 ona curved rod 34 engages a lug 35, and yields enoughA to permit the carrier to turn properly, as clearly shown in Fig. 6.

The cut-ott' strips are transferred from the point of cut-off to the strip-carriers by a device of the type shown in the patent to Starman No. 658,930 dated Oct. 2, 1900, vto

which reference may be had as to Adetails re lating to the strip-engaging dogs, etc.- For the purposes of this application the device may be briefly described' as follows: between the bars of a yoke 30 are attached .tingers 37 adapted to receive -betweenthem the severed strip. The strips as cut olf are first held by dogs at 88, and again, when advanced' part way to the strip-carriers, by other dogs at 39. Near the ends of the yoke 36 are' attached guide-rods 40, secured at their other ends to another yoke 4l. On the guide-reds is mounted a crosshead 42 similar to the yoke 3G, and to 1t are attached pairs of fingers 43 in the same manner. These are in the secondary operation, into engagement with the rows of slotted stri s in' said carriers. In Fig. 3 the spring ngers are not shown, but the engagement of the strips is clearly illustrated. .ln this figure the strips are supposedto be about half way advanced toward .interinatching position. Suitable Haring guides are provided at 46 and 47 to keep the ends of the strips in proper osition. Detent pawls 45 prevent the strips from slipping back from the carriers.

Since the gang of strip carriers has a con tinuous forward movement, provision is made for imparing a correlative movement to the strip-conveying device.v Both the yoke 30 and the crosshead are providedwith trunnions 4S and 49, respectively. The former are mounted iii-suitable bearings 50 attached to someA xed portion of the machine. This allows the whole frame to rock. The trunnions of the crosshead are mounted in bearings lslidabl;7 mounted in levers 524 attached to a rock-shaft 53 journaled at 54. lThese levers connect suitably with eccentries and are thus given a reciprocating movement at each impulse'of the machine. ',lo the front (inner) yoke of the conveyer frame is attached a pair of brackets 5G, each carrying a'pawl adapted to engage va specialratchetnvhe'el 57, the movement of whose teeth exactly coincides with the movement of lthe carriers. It will be noted that the pawl shown in Fig. 3 is adapted to :be carried downwardly bythe ratchet-wheel, while that shown at the right in Fig. 1 is adapted to be carried in the opposite direction. f For the sake of nice adjustment the toothfengaging block 5S of the pawl 59 may be moved by 'transfer frame needs to move in unison with than 'is possible when thecarriers are ad- ,course true of the train of strip-carriers and `their actuating mechamsm.

mea-ns of a temper sc rew 60. Each dog has a curved extension at 6l to engage a roller 62 mounted in the path of the pawl on one of the carrier guides. This releases the pawl when the strip has been inserted in the carrier, and permits the conveyer frame t return toinitial position,'when the pawl en- .gages another tooth of the-ratchet-wheel.

The frame is returned by springs 63 on rods 64 passing through a lug 65 and a plate 66, the latter attached to the main frame. Below this plate is another sprin G7, which," in connection with a weighted ever 68 abf sorbs the shock of the rebound. As the the carriers during but a short interval the 8O frame has plenty of time in which to ret-urn to initial position. j

l't is to be understood that the ratchetwheel so provided is mounted on a shaft 69 driv'en hy gears 70, 7l and 72. This feed device tcndsto impart a very smooth and perfect action to the machine, and admits of its being run at a higher rate of speed vanced intermittently. This will be evident lfrom thefact that the transfer devices are comparatively light, and their inertia is easily overcome, while the contrary is of' To insure the complete bottoming of the strips, beaters 73 are attached Ato the arms that move the strips.v to the carriers. These are mounted respectively above and below the strip as enterehony opposite sides of the `machine, and as they strike the edge of the previously inserted strip drive it to complete intermatehing position.

The completed cell-case is ejected downwardly, as indicated in Fig. 2. The mechanism for this purpose is described as follows: On each sideof the lower main sprocket is mounted a four-arm spider 74, each arm provided with a movable plunger 75. Each plunger has outwardly projecting push-pins 77 .registering with holes 78 in the bottomplate of each strip-carrier. These pins, as will appear by reference to Fig. 4, coincide l' with intersections ofstrips in the cell-vease. To the shaft of each plunger is mounted a roller adapted to travel along a groove 76 in one face of a cam 7 9 mounted loosely on the shaft 24. The cam connects with a rod 80, and this with alever Slpivotedat some fixed point, as to apart of the main frame, as-shown in' Fig. 2a. The lever carries a roller 82 traveling on the face of a four-point cam 83 fixed to' the central shaft 69. The' action of the ejector is indicated in F ig. 2. The carrier and ejectors move downwardlv in unison, and 'as the latter follows the lower cam the push-pins areof course forced out` wardly and ,intQ the holes in the carrier plate. During a goed part of thi'smovenient 130` the lowercam remains'sta'tionary and in i practically the position shown. The' forf tically stiff finiger A,

ward movement of the carriers is, however, comparatively "slow, and 1t is desirable to eject the completedcell-case ratherquickly, to avoid. possible catching and drag mg. This is'eectedby the sudden action o `the rather abrupt upper cam, which, at the proper time throws uythe lever 81, and this rings the lower cam ack with a jerk, forcing the cell-case out of the carrier cleanly -and quickly.

vSince the construction described permits of high speed in the machine, it is very .im--

portant that in m'atch strips the intersecting slots come into pretty accurate register. This'dcpends largely upon the strip-holding fingers, and in practice the fingers shown in Fig. 7 have been found to serve the purpose very perfectly. They consist of a pracbent outwardly at A, and .-a spring nger B curved as shown, so tha't its bulge strikes about midway of the width of the strip when in intermatching position.- This pressing against the convex side of the strip C'brings the strip up fiat against' the straight side of the stiiffinger,

and'holds the strip accurately in'position It isto be noted that this is done with comparatively little s ring-finger with the Istrip, so that while t eistrip 1s held firmly enough 'for inter- I. matching the grip of the fingers is not so great as to prevent the ejector from dis-A charging'the finished filler without bending or mutilating it.
